On Jan. 11, 1964, U.S. Surgeon General Luther Terry released a report linking smoking to lung cancer.

The findings of the report would have significant consequences for health policy, attitudes toward smoking and, ultimately, how smoking was depicted in television commercials.

USA TODAY Network looks back at how cigarettes were portrayed in television commercials and in movies during smoking's heyday -- and how tobacco's portrayal in TV ads 50 years after the surgeon general's report is vastly different.
